Angostura Bitters is no joke

That's an entire shot of Angostura. You have to remove the drip cap from the bottle to get this kind of intense beauty.

You can’t really have a cocktail bar without a bottle of Angostura bitters.

Typically, only a couple tiny drops of this dark, bitter concoction are called for in classic recipes like the Old Fashioned—but those droplets are indispensible.

It also happens to be stellar in coffee, cooking, and baking, just to name a few of its other application. For such a tiny bottle, it’s kind of a big deal. And its complex recipe is a heavily guarded secret which was created in the midst of raging revolutions and crackling rifles.
